Only 24 hours after former House Speaker Andrew Romanoff launched his campaign, the president bigfooted his way into the primary, issuing a glowing endorsement of current U.S. Sen. Michael Bennet. . . We were somewhat surprised to see the president of the United States jump into the intra-party fray so soon. He barely had time to bone up on Romanoff's accomplishments (we say a bit sarcastically). . .

Obama has jumped into other primaries, as well. He endorsed Sen. Arlen Specter, the Pennsylvania Republican-turned-Democrat, in his bid against a more liberal opponent. The president also gave a quick thumbs up to Sen. Kirsten Gillibrand when there was a chance she might be challenged by another Democrat for Hillary Rodham Clinton's old New York Senate seat.

Still, Obama doesn't know who the best candidate is for Colorado. The issues in this race haven't even been broached. Certainly we have no problem with the president endorsing someone - in fact, we like to do it, too - but c'mon, let's have a campaign first. [via David Sirota ]
